Schlage 09-638L 612 KN – Frequently Asked Questions

1) What exactly is the Schlage 09-638L KN and what does it replace?
It's the outside escutcheon trim plate for a Schlage L Series mortise lock, in the concealed cylinder by knob configuration. It is the plate only, a genuine Schlage replacement part, so you use it to restore damaged or mismatched exterior trim without pulling and replacing the whole L Series mortise lockset. The lock body, knob, and cylinder are separate items.
2) Will the 09-638L KN fit a Schlage L Series lever trim?
No. This escutcheon is the knob version of the L escutcheon, cut for a knob spindle and a concealed cylinder. If your opening runs L Series levers, you need the lever escutcheon instead. Check which one is on the door before ordering, since the two are not interchangeable.
3) Is the Schlage Electronics 47260707 CO Series escutcheon a substitute for the Schlage 09-638L KN?
No. The 09-638L KN is a mechanical concealed cylinder x knob L escutcheon for Schlage L Series exterior locksets, with no electronics in it. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks in the CO100 platform and is a keypad unit, supplied with fasteners and O-ring. If the door carries a keyed L Series mortise lock, the 09-638L KN is the matching trim; the 47260707 only fits a CO Series access-control opening.
4) Which finishes does the Schlage 09-638L KN escutcheon come in so I can match my other doors?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless, and 630 satin stainless. For a building already standardized on Schlage commercial trim, 626 satin chrome and 630 satin stainless are the two you'll most often be matching.
5) Is this the inside or outside escutcheon for an L Series lock?
Outside. The 09-638L KN is the exterior escutcheon, which is why it carries the concealed cylinder prep. The interior plate is a separate part, so if you are refinishing both sides of the door you need to order trim for each side.
6) Does concealed cylinder mean the key cylinder is included with this escutcheon?
No cylinder comes with it. Concealed cylinder describes the escutcheon's prep, where the mortise cylinder sits behind the plate rather than showing a visible collar. You reuse the existing cylinder from the lock, or order one separately keyed to your system.
7) I need an exterior escutcheon for exit device trim, not a mortise lock - what should I look at instead of the 09-638L KN?
The 09-638L KN is built to the L Series trim geometry for exterior mortise lockset applications, so it is not the part for an exit device. For exit trim, the Schlage Electronics 47260708 is a CO Series exterior escutcheon for exit trim on the CO-100 platform, a keypad unit offered in aged bronze. Choose it when the opening is an exit device with electronic access control; stay with the 09-638L KN when the opening is a keyed L Series mortise lock.
8) Will an MS Sedco ESC escutcheon plate work in place of the Schlage 09-638L KN?
No. The MS Sedco ESC is a decorative stainless escutcheon plate made for R4 and R6 round switches, so it belongs behind a push switch rather than a lockset. The Schlage 09-638L KN is a commercial replacement escutcheon for Schlage L Series exterior locksets in a concealed cylinder x knob configuration. The two share only the word escutcheon; the prep and the hardware behind them are different.
9) If I want to match an existing chrome or stainless trim run, which escutcheon gives me more finish choice?
The Schlage 09-638L KN covers eight architectural finishes, including 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel, alongside brass and bronze options. By comparison, the Schlage Electronics 47260708 CO Series exit trim escutcheon is catalogued in aged bronze. For standardizing a chrome or stainless corridor on L Series mortise hardware, the 09-638L KN is the one with a direct finish match.
10) Is this escutcheon rated for commercial traffic or is it a residential part?
Commercial. It is built for L Series mortise hardware in offices, schools, healthcare, retail, government buildings, industrial facilities and multi-tenant residential, which is the traffic level L Series trim is specified for.
11) Can I use this Schlage escutcheon to cover an old cutout or mount a push-button switch?
No, it's cut to the L Series trim geometry and only lines up with L Series mortise prep. For covering a round push switch, the MS Sedco ESC decorative stainless escutcheon plates are made for R4 and R6 round switches. Using lock trim as a filler plate won't line up with the holes.
